Inventor: MACK MICHAEL EDWARD
IPC: H01J37/317
Filed: 1999-11-18
Granted: 2001-05-16
Abstract: In accordance with the present invention, an ion implanter (10) including a rotatable support (110) disposed in an implantation chamber (17) of an ion beam implanter (10) for supporting a plurality of wafer workpieces (100). The rotatable support (110) includes a hub (112) adapted to be rotated about an axis of rotation (CL) substantially parallel to a direction of an ion beam beam line (18) entering the implantation chamber (17). The rotatable support (110) further includes a plurality of wafer support members (120) adapted to be attached to the hub (112), each wafer support member (120) adapted to support at least one of the wafer workpieces (100). Each wafer support member (120) includes an attachment structure (150) for affixing the support member (120) to the rotating hub (112) and a wafer support pad (130) extending from the attachment structure (150) and passing through the beam line (18) as the hub (112) rotates. The wafer support pad (130) includes a wafer support surface (132) facing the beam line (18) that includes a concave portion. Preferably, the concave portion of the wafer support surface (132) is cylindrically shaped and a central axis of an imaginary cylinder (IC) partially formed by the concave portion intersects an axis of rotation (CL) of the hub (112). A radius of curvature (R) of the concave portion is large, for a 300 mm. Disk shaped wafer, the radius of curvature (R) is 7 meters. Each wafer support member (120) further includes a clamp (200) for releasably securing a wafer workpiece (100) to the wafer support pad (130). Upon rotation of the hub (112) at a predetermined angular velocity, the workpiece (110) conforms to a shape of the concave portion due to a component of centrifugal force normal to a surface of the wafer support surface (132).

Title: Method for forming a barrier layer for use in a copper interconnect
Inventor: DENNING DEAN J
IPC: C23C14/14
Filed: 2000-02-16
Granted: 2001-11-21
Abstract: A method for forming an improved copper inlaid interconnect (FIG. 11) begins by performing an RF preclean operation (408) on the inlaid structure in a chamber (10). The RF preclean rounds corners (210a and 206a) of the structure to reduce voiding and improve step coverage while not significantly removing copper atoms from the underlying exposed copper interconnects surfaces (202a). A tantalum barrier (220) is then deposited where one portion of the tantalum barrier is more tensile than another portion of the tantalum barrier. After formation of barrier layer (220), a copper seed layer (222) is formed over a top of the barrier layer. The copper layer is formed while clamping the wafer with an improved clamp (85) which reduces copper peeling and contamination at wafer edges. Copper electroplating and chemical mechanical polishing (CMP) processes are then used to complete the copper interconnect structure.

Granted: 2002-07-21
Abstract: The invention relates to a construction method making use of concrete for application in an integral process containment vessel where the entire or part of large-scale vertically stacked multi-effect distillation desalination processes take place. According to the present disclosure, such an integral process containment concrete vessel is divided into at least two different process zones, where each process zone marks a different degree of severity of attack under respective process conditions. In each of the said zones, the part of the integral process containment vessel that is in direct contact with the process conditions is constructed by means of a concrete mix that is matched to the process conditions in the said zone. Thus the resultant prestressed integral process containment vessel, constructed by means of a multi-layer, and/or multi-segment method or by means of jump-forming, slip-forming, climb-forming or the like, is functionally graded with at least two different concrete mixes processing significantly different properties and therefore costs and thereby arriving at a durable and cost effective construction method.

Title: Method for depositing a protective film on a data recording disk and apparatus for depositing a thin film on a data recording disk
Inventor: SASAKI HIROMI
IPC: C23C14/56
Filed: 2000-06-12
Granted: 2002-08-11
Abstract: This invention relates to a method for depositing a protective film on a data recording disk and an apparatus for depositing a thin film on a data recording disk. That is to solve problems produced by the different optimal manufacture conditions for preparing a magnetic film before the protective film and for preparing the protective film. A middle heating chamber 8 is airtightly connected between a magnetic film formation chamber 5 and a protective film formation chamber 6 in which a carbon protective film is formed by plasma chemical vapor deposition utilizing the decomposition of a gaseous hydrocarbon compound in high-frequency discharge plasma while applying negative bias voltage to a substrate 9 with a bias applying mechanism. The substrate 9 is heated with a radiant heating lamp in the middle heating chamber 8 in such a way that a protective film formation temperature is higher a magnetic film formation temperature and is attained after the formation of a magnetic film. Therefore, an information recording disk with a carbon protective film having high hardness laminated on a magnetic film having high coercive force is obtained.

Title: System and method for a variable gain proportional-integral (PI) controller
Inventor: VYERS EMMANUEL
IPC: G05B13/02
Filed: 2000-07-10
Granted: 2002-06-11
Abstract: A method for generating a valve drive signal using a variable gain PI controller in a mass flow controller. The method includes multiplying an error signal with a proportional gain factor to generate a proportional signal. The method also includes implementing an integral function on the error signal. The integral function includes an integral gain factor which functions as the variable gain in the PI controller. For set-point signals less than a normalized predetermined percentage of the maximum set-point, the gain factor is equal to [(1/0.1-1)A+B], where A is a first gain constant and B is a second gain constant. Otherwise, the integral gain factor is [(1/x-1)A+B], where A is the first gain constant, B is the second gain constant, and x is the normalized set-point signal. Implementing the integral function produces an integral signal. Lastly, the integral signal and the proportional signal are summed to generate the valve drive signal. The error signal is a function of the difference between a set-point signal and a feedback signal. The set-point signal is a function of a desired flow rate in the mass flow controller, while the feedback signal is a function of the actual flow rate through the mass flow controller.

Title: Selective address table aging in a network switch based on application state determined from a received data packet
Inventor: KANURI MRUDULA
IPC: H04L12/46
Filed: 2000-09-06
Granted: 2005-05-11
Abstract: A network switch, configured for performing layer 2 and layer 3 switching in an Ethernet (IEEE 802.3) network without blocking of incoming data packets, includes a network switch port having a packet classifier module configured for evaluating an incoming data packet on an instantaneous basis. The packet classifier module performs simultaneous comparisons between the incoming data stream of the data packet and multiple templates configured for identifying respective data protocols. Each template is composed of a plurality of min terms, wherein each min term specifies a prescribed comparison operation within a selected data byte of the incoming data packet. Hence, the packet classifier module is able to monitor data flows between two network nodes interacting according to a prescribed network application. The packet classifier module determines the application state for a prescribed network application from a received layer 2 data packet, enabling switching logic within the network switch to utilize application-specific aging intervals for respective network applications such as HTTP, SNMP, ftp, Telnet, etc. in order to delete aged address entries from a network switch address table based on the supported network application. Determination of the application state from the received layer 2 data packet also enables the network switch to detect the end of a data flow for deletion of the corresponding address entry from the network switch address table.
